DETAILED DESCRIPTION

[0040] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] The present application provides a vertical box opening machine for automatically completing the processes of material taking, box opening, page closing and conveying of folded packaging boxes, thereby improving production efficiency and product quality.

[0042] As shown in Figures 1-2 , the vertical box opening machine in the present embodiment mainly includes important components such as a material taking assembly 200, a box opening assembly 300, a bracket 400 and a page closing assembly 500, and is also equipped with an ejection assembly 600 and a workbench 800 to support the overall operation, aiming to replace traditional manual operation through mechanical automation means to realize rapid and accurate opening and packaging of packaging boxes. The overall structure is compact, and each part works cooperatively to ensure smoothness in the whole process from material taking to finished product output.

[0043] As shown in Figure 1 and Figure 2 , the present embodiment further includes an ejection assembly 600 and a workbench 800. The ejection assembly 600 is located at the end of the bracket 400, and its structure includes an ejection cylinder, and a discharge port is provided on the side of the bracket 400 opposite to the ejection cylinder. When the packaging box completes all processing procedures, the ejection cylinder is started under the instruction of the control system to eject the packaging box from the bracket 400, and then the packaging box falls into a collection box or a conveying belt through the discharge port.

[0044] The workbench 800 is used to carry the aforementioned components and provides a stable support platform for the entire vertical box opening machine. The design of the workbench 800 takes into account the overall structure and layout of the equipment, and through reasonable size and shape design, the components can be closely matched together to form a complete and efficient production line.

[0045] As shown in Figure 3As shown, the storage rack 100 in this embodiment includes a rack 101, and the folded packaging boxes are arranged side by side on the rack 101. A sliding push plate 102 is arranged on the rack 101 to push the packaging boxes to move. The sliding push plate 102 is driven by a rodless air cylinder to realize feeding one by one. The design of the storage rack 100 fully considers the storage and feeding efficiency of the packaging boxes. The rack 101 serves as a storage carrier and can accommodate a large number of packaging boxes in a folded state to meet the needs of continuous production. The design of the sliding push plate 102 realizes automatic pushing of the packaging boxes through the driving of the rodless air cylinder, which not only ensures the accuracy of feeding but also improves the production efficiency. The one-by-one feeding mode avoids the accumulation and confusion of the packaging boxes and ensures the smooth operation of the production line.

[0046] As shown, Figure 3 The feeding assembly 200 in this embodiment includes a reciprocating suction cup assembly 203 for transferring the folded packaging boxes on the storage rack 100. The feeding assembly 200 is the starting link of the unpacking machine and is responsible for accurately and quickly picking up the packaging boxes in a folded state from the storage rack 100. The suction cup assembly 203 firmly grabs the packaging boxes through the principle of vacuum adsorption to ensure that they will not fall or shift during movement. The reciprocating design enables the suction cup assembly 203 to work continuously within a fixed stroke, improving the feeding efficiency.

[0047] Specifically, the feeding assembly 200 includes a first sliding seat 202, which is slidingly arranged on a sliding rail and is driven to displace by a first telescopic drive 201. The suction cup assembly 203 is fixed to the first sliding seat 202 by a connecting rod, and the suction cup assembly 203 includes at least one suction cup. The first sliding seat 202 serves as a moving carrier and realizes reciprocating movement within a fixed stroke through the cooperation of the sliding rail and the first telescopic drive 201. The suction cup assembly 203 is fixed to the first sliding seat 202 by the connecting rod to ensure the synchronous movement of the suction cup and the sliding seat. The number and layout of the suction cups can be adjusted according to actual needs to meet the feeding needs of packaging boxes of different sizes and shapes. This design is flexible and practical, greatly improving the adaptability and reliability of the feeding assembly 200.

[0048] The driving assembly 700 in this embodiment includes a rotary driving device, a driving pulley, and a transmission belt. The sliding seat is connected to the transmission belt by a first fixed clamp plate 313. The rotary driving device serves as a power source and realizes the stable movement of the sliding seat through the cooperation of the driving pulley and the transmission belt. The design of the first fixed clamp plate 313 ensures the close connection between the sliding seat and the transmission belt, preventing sliding and falling during transmission. This design is simple and practical, effectively improving the transmission efficiency and stability of the unpacking assembly 300.

[0049] As shown, Figure 4 and Figure 5As shown, the opening box assembly 300 in this embodiment, which coincides with one end of the taking component 200, includes two sliding seats (the second sliding seat 301 and the third sliding seat 302) that move reciprocally in the same direction and can be relatively displaced, one of which is connected with a frame structure, the frame has a fixed push rod 304 and a rotatable movable push rod 307, and the other sliding seat is provided with a driving connecting rod for receiving, opening and conveying the packaging box.

[0050] The opening box assembly 300 is responsible for unfolding the folded packaging box and conveying it to the next process. The relative displacement design of the two sliding seats enables the fixed push rod 304 and the movable push rod 307 to closely cooperate, realizing accurate clamping and unfolding of the packaging box. The rotating design of the movable push rod 307 not only ensures the smoothness of the opening action, but also avoids damage to the packaging box during the conveying process. The driving connecting rod converts the relative displacement of the sliding seat into the rotary motion of the movable push rod 307, thereby realizing the opening action.

[0051] Specifically, the two sliding seats are connected through a sliding shaft 312, realizing reciprocating movement in the same direction. One of the sliding seats is fixedly connected with the driving assembly 700 and moves autonomously through the driving of the driving assembly 700. The design that the moving direction of the sliding seat forms a 90-degree angle with the moving direction of the taking component 200 enables the opening box assembly 300 to immediately perform the opening operation after the taking component 200 completes the taking, improving the continuity and efficiency of the production line.

[0052] The frame structure in this embodiment includes one support 303 and at least one connecting seat 306 arranged in parallel, and the support 303 and the connecting seat 306 are connected with each other through at least one support shaft 305, the support 303 is connected with the fixed push rod 304, and the connecting seat 306 is connected with the movable push rod 307. The minimum distance between the fixed push rod 304 and the movable push rod 307 is the same as the width of the clamped surface of the packaging box. The parallel arrangement of the support 303 and the connecting seat 306 ensures the stable support of the fixed push rod 304 and the movable push rod 307, and better clamping on the two side surfaces of the packaging box.

[0053] The design that the minimum distance between the fixed push rod 304 and the movable push rod 307 is the same as the width of the clamped surface of the packaging box ensures the tightness and accuracy of clamping. When the number of movable push rods 307 is two, the movable push rod 307 close to the fixed push rod 304 moves towards the fixed push rod 304 and cooperates with the fixed push rod 304 to unfold the folded packaging box, and the other movable push rod 307 is responsible for pushing the opened packaging box to the bracket 400. This design improves the opening efficiency and ensures the integrity and accuracy of the packaging box.

[0054] The driving link in the embodiment comprises at least one connecting shaft (the first connecting shaft 308 and the second connecting shaft 309) connected to the other sliding seat, and the connecting shaft is connected with the movable push rod 307 through the first link assembly 310, and the relative displacement of the two sliding seats can realize the rotation of the movable push rod 307.

[0055] In the embodiment, the number of connecting shafts is two, which are the first connecting shaft 308 and the second connecting shaft 309, respectively corresponding to the two movable push rods 307 in the embodiment. The two connecting shafts are connected with the two corresponding movable push rods 307 through the first link assembly 310, which ensures that the relative displacement of the sliding seats can be converted into the rotary motion of the movable push rod 307. With the relative displacement of the two sliding seats, the driving link drives the movable push rod 307 to rotate towards the side of the fixed push rod 304, thereby realizing the clamping and unfolding of the packaging box, and also realizing the conveying of the packaging box after the box is opened. This design is simple and practical, and effectively improves the reliability and stability of the box opening assembly 300.

[0056] In addition, the fixed push rod 304 is designed with a avoiding hole for the docking suction cup assembly 203 to avoid mutual interference. After the suction cup assembly 203 clamps the material and moves to the position of the fixed push rod 304, the fixed push rod 304 can convey the packaging box to the next process at this time.

[0057] As shown in Figures 6-8 The bracket 400 in the embodiment is docked with the box opening assembly 300 to receive the packaging box after the box is opened. The bracket 400 comprises two groups of rotating rollers 401, which are arranged at intervals. The packaging box is between the two groups of rotating rollers 401 and is connected through friction to avoid falling. The design of the bracket 400 takes into account the stability of the packaging box during conveying. The interval arrangement of the two groups of rotating rollers 401 not only ensures that the packaging box can pass smoothly, but also provides the necessary support force through friction to prevent the packaging box from falling or tilting during conveying. This design is simple and practical, and effectively improves the reliability and stability of the conveying.

[0058] As shown in Figures 6-8 The closing page assembly 500 in the embodiment is located on one side of the bracket 400 and extends to the upper and lower ends of the bracket 400, and comprises a top rod 501, a push rod 502, an insertion plate 510 and an insertion piece assembly, which are used to close the flaps and bottom cover of the packaging box.

[0059] The closing page assembly 500 is responsible for completely closing the packaging box after the box is opened. The design of the top rod 501 and the push rod 502 is responsible for closing the flaps at the lower end and the other side of the packaging box in the forward direction, respectively, to ensure that the flaps can be tightly fitted. The insertion plate 510 and the insertion piece assembly are responsible for inserting the bottom cover flap into the packaging box to realize the sealing of the bottom cover. The whole closing page process has high automation degree, which greatly improves the production efficiency and product quality.

[0060] The top rod 501 in the embodiment is arranged below the bracket 400 and parallel to the bracket 400, closes the end flap of the packaging box in the advancing direction, and is provided with an upward inclined surface on the side facing the packaging box, which facilitates folding the corresponding flap and prevents damage to the surface of the packaging box.

[0061] The push rod 502 in the embodiment is arranged between the top rod 501 and the material taking assembly 200, and closes the other end flap of the packaging box by rotating. The push rod 502 is connected with a push rod cylinder 5022 through a second connecting rod assembly 5021, and the rotation of the push rod 502 in the vertical direction is realized by the extension and retraction of the push rod cylinder 5022, which realizes the closing of the flap of the packaging box without affecting the movement of the packaging box. The push rod 502 is connected with the push rod cylinder 5022 through the second connecting rod assembly 5021, which ensures the rotation of the push rod 502 in the vertical direction. The extension and retraction of the push rod cylinder 5022 drives the rotation of the push rod 502, thereby realizing the closing of the other end flap of the packaging box. This design not only avoids the interference of the push rod 502 with the packaging box when closing the flap, but also improves the efficiency and accuracy of closing the flap.

[0062] The flap closing assembly 500 further comprises a fixed frame 504, which comprises an L-shaped structure including a horizontal segment and a vertical segment. The horizontal segment of the fixed frame 504 is provided with a fourth sliding seat 509 moving horizontally. The fourth sliding seat 509 is connected with a second extension drive 5091 and moves in a direction perpendicular to the side wall of the bracket 400. A plug plate 510 is fixed on the fourth sliding seat 509 through a support.

[0063] The fixed frame 504 serves as a support structure and is designed in an L-shaped structure, which provides a horizontal segment for mounting the fourth sliding seat 509 and a vertical segment for mounting other flap closing components. The fourth sliding seat 509 moves horizontally through the second extension drive 5091, which ensures that the plug plate 510 can accurately drive the bottom cover flap of the packaging box to flip. The plug plate 510 is fixed on the fourth sliding seat 509 through a support, which ensures the synchronous movement and stability of the plug plate 510 and the fourth sliding seat 509. This design improves the reliability and stability of the flap closing assembly 500.

[0064] In another embodiment, the closing page assembly 500 also includes a positioning device for intermittently positioning the packaging box. Since the upper and lower ends of the bracket 400 are both open structures, if the packaging box is not positioned during the closing page process, it will affect the subsequent positioning effect. The positioning device includes a page clamping assembly 505 and a claw 5092. The page clamping assembly 505 is connected to the vertical section of the fixed frame 504 through a support and moves vertically. It includes two connecting pieces that are close to each other and consistent with the movement direction of the packaging box, and correspond to the movement path of the top cover page of the packaging box. The two connecting pieces expand outward on the side close to the packaging box to facilitate clamping and positioning the top cover page of the packaging box. This design enables the page clamping assembly 505 to firmly clamp the top cover page of the packaging box, preventing it from moving left and right during subsequent processing, thereby ensuring the positioning accuracy of the packaging box. At the same time, the vertical movement design of the page clamping assembly 505 also facilitates adjustment according to packaging boxes of different sizes, improving the versatility of the equipment.

[0065] The claw 5092 in this embodiment is connected to the fourth sliding seat 509 through a support and intermittently positions and clamps the packaging box as the fourth sliding seat 509 moves. The claw 5092 utilizes the movement characteristics of the fourth sliding seat 509. When the fourth sliding seat 509 moves towards the bracket 400, the claw 5092 can restrict the movement of the packaging box in the forward direction, ensuring that the packaging box remains stable when the plug-in plate 510 is inserted into the bottom cover page. When the fourth sliding seat 509 is retracted, the claw 5092 releases the restriction on the packaging box, allowing it to continue moving forward and enter the next processing link. This intermittent positioning method not only ensures the stability of the packaging box during processing, but also improves the processing efficiency of the equipment.

[0066] The positioning device ensures accurate positioning of the packaging box during processing, providing strong support for subsequent processes such as insertion of the plug-in plate 510 and closure of the bottom cover page. The use of the page clamping assembly 505 and the claw 5092 not only improves the positioning accuracy of the packaging box, but also effectively prevents displacement or deformation of the packaging box during processing due to external forces, thereby ensuring the processing quality of the product. In addition, the intermittent positioning method of the positioning device also enables the equipment to process packaging boxes more efficiently, improving the overall production capacity of the production line.

[0067] In addition, in order to further improve the stability and reliability of the positioning device, a guide rail is provided on the vertical section of the fixed frame 504 to guide the vertical movement of the page clamping assembly 505. The design of the guide device not only ensures the movement accuracy of the page clamping assembly 505, but also effectively prevents it from shaking or deviating during movement, thereby improving the overall performance of the equipment.

[0068] The insert assembly in this embodiment includes a first insert 507 and a second insert 508. The first insert 507 and the second insert 508 are connected to corresponding drive cylinders (specifically, first insert drive cylinder 5072 and second insert drive cylinder 5082) through connecting rods (specifically, first connecting rod 5071 and second connecting rod 5081), respectively. This design allows the inserts to move up and down vertically, thereby achieving precise control over the insertion of the bottom cover flap tongue of the packaging box. The design of the insert assembly takes into account the need for precise control of force and position during the folding and insertion of the packaging box bottom cover tongue. Through cylinder drive and connecting rod transmission, stable movement of the inserts in the vertical direction can be ensured, avoiding damage to the packaging box and improving work efficiency.

[0069] The main function of the first insert 507 in this embodiment is to fold the bottom cover flap tongue. When the packaging box is conveyed to the designated position, the first insert 507 moves downward under the drive of the cylinder, contacts the bottom cover flap tongue, and applies a certain pressure to fold it to 90 degrees. This action is a key step in the sealing process of the packaging box bottom cover, providing preparation for the subsequent insertion of the tongue. The shape and size of the first insert 507 are designed according to the specific shape of the packaging box bottom cover flap tongue to ensure smooth folding. At the same time, the driving force and movement speed of the cylinder are adjustable to adapt to packaging boxes of different materials and thicknesses, improving the versatility of the equipment.

[0070] The second insert 508 in this embodiment is used to move the bottom cover flap and the tongue upward and seal the bottom of the packaging box. After the first insert 507 completes the folding of the tongue, the second insert 508 moves upward under the drive of the cylinder, pushing the bottom cover flap and the folded tongue into the packaging box together, thereby achieving the sealing of the bottom cover. The movement distance and speed of the second insert 508 are also precisely controlled to ensure that the bottom cover flap and the tongue can be accurately inserted into the packaging box, while avoiding excessive pressure or damage to the packaging box. This design not only improves the sealing of the packaging box, but also ensures the appearance quality of the product.

[0071] The page assembly 500 not only includes components for clamping and pushing the packaging box, but also includes a drag rod 506. In this embodiment, the drag rod 506 is connected to the transmission belt through a connecting rod and a second fixed clamp plate 5061. This connection allows the drag rod 506 to move with the transmission belt, achieving intermittent support for the packaging box. The design of the drag rod 506 takes into account the stability of the packaging box during the conveying process. When the lower end of the packaging box loses the support of the push rod 501 and the drag rod 502, the two flaps below the packaging box will open if not supported, affecting the subsequent turning of the bottom cover flap. Through the drive of the transmission belt, the drag rod 506 can move to the lower end of the packaging box at a specific moment to provide support.

[0072] The longitudinal section of the drag bar 506 is a right triangle, with the hypotenuse facing the insert plate 510. That is, its upper end is at a right angle to the end near the first insert plate 507. The top continuously presses down on the two side panels at the bottom of the packaging box, thereby achieving continuous closure of the folds on both sides of the packaging box. At the same time, the lower end line of the drag bar 506 is on the same vertical plane as the fold line of the insert tongue, which facilitates the first insert plate 507 to drive the insert tongue to bend, ensuring the smooth bending and insertion of the insert tongue.

[0073] The first insert 507 is located on one side of the drag bar 506 and works with the drag bar 506 to bend the tab. When the insert plate 510 flips the bottom cover flap of the packaging box to a certain height, the fold line of the tab coincides with the lower end line of the drag bar 506. The first insert 507 moves downward under the drive of the cylinder, bending the tab of the bottom cover flap to 90 degrees. After bending, since the drag bar 506 is connected to the transmission belt, it moves away as the transmission belt moves. At this time, the second insert 508 moves vertically under the drive of the cylinder, inserting the bottom cover flap into the packaging box. The cooperation between the first insert 507 and the drag bar 506 enables the continuous operation of the tab bending and bottom cover insertion. This design not only improves work efficiency but also ensures the accuracy and stability of the operation. At the same time, the removal of the drag bar 506 provides sufficient space for the insertion of the second insert 508, avoiding interference between components.

[0074] In this embodiment, in order to save space, the first insert 507 and the second insert 508 are both connected to the first insert drive cylinder 5072 and the second insert drive cylinder 5082 through the corresponding first connecting rod 5071 and the second connecting rod 5081, so that multiple cylinders are brought together to facilitate subsequent driving.

[0075] In this embodiment, as Figure 7 As shown, the closing assembly 500 also includes a rotatable push plate 503. The push plate 503 is rotatably connected to a rotating shaft 5031, and the rotating shaft 5031 is connected to a fourth sliding seat 509 via a third linkage assembly 5032. This design allows the push plate 503 to rotate under the drive of the fourth sliding seat 509, thereby continuously pushing the packaging box to move. Through the movement of the fourth sliding seat 509 and the transmission of the third linkage assembly 5032, the push plate 503 can smoothly push the packaging box forward, avoiding any stagnation or jamming during the conveying process.

[0076] With the movement of the fourth sliding seat 509, the push plate 503 rotates and continuously pushes the packaging box, conveying it to the next station. This design not only ensures the continuity of the production line, but also improves the work efficiency. The rotation speed and pushing force of the push plate 503 are adjustable to adapt to packaging boxes of different sizes and weights. This flexibility makes the invention applicable to various types of packaging box processing, improving the versatility and practicality of the equipment.

[0077] The specific working principle is as follows:

[0078] The folded packaging box is placed on the shelf 101, and under the drive of the rodless cylinder, the sliding push plate 102 pushes the packaging box towards the material taking assembly 200, so that the material taking assembly 200 can grasp the packaging box through the suction cup assembly 203 within its moving stroke;

[0079] After the material taking assembly 200 grasps the packaging box, it moves towards the opening assembly 300. When it reaches the end of the stroke, the two sliding seats (specifically the second sliding seat 301 and the third sliding seat 302) are in relative displacement, and the packaging box is clamped by the fixed push rod 304 and the rotating push rod (composed of the connecting seat 306, the movable push rod 307, the first connecting shaft 308, the second connecting shaft 309, and the first connecting rod assembly 310). In addition, since the minimum distance between the fixed push rod 304 and the rotating push rod is the width of the clamped surface of the packaging box, the packaging box is also unfolded by the clamping action of the rotating push rod and the fixed push rod 304, and the two sliding seats move synchronously to transport the opened packaging box towards the cradle 400;

[0080] At this time, the lower end of the packaging box advances to contact the top rod 501, thereby achieving closure. Then, driven by the push rod cylinder 5022, the push rod 502 rotates in the vertical plane to drive the closure of the other side of the packaging box. With the continuous movement of the packaging box, the drag rod 506 is then moved to the lower end of the packaging box under the drive of the drive assembly 700 to continuously close the flaps on both sides;

[0081] With the continuous movement of the packaging box, the flap clamping assembly 505 in the positioning device can clamp the top cover flap of the packaging box. At the same time, the second telescopic drive 5091 drives the movement of the fourth sliding seat 509, and the pawl 5092 can also contact the packaging box, thereby double positioning the packaging box;

[0082] At the same time, the insertion plate 510 also drives the bottom cover flap to flip with the movement of the fourth sliding seat 509;

[0083] The first insertion sheet 507 moves in the vertical direction under the action of the first insertion sheet driving cylinder 5072, and in combination with the shape of the drag link 506 and the positional relationship between the drag link 506 and the first insertion sheet 507, the first insertion sheet 507 bends the insertion tongue of the bottom cover flap to 90 degrees at this time;

[0084] Subsequently, the drag link 506 is driven by the driving assembly 700 to be separated from the bottom cover flap, and the second insertion sheet 508 moves in the vertical direction under the driving action of the second insertion sheet driving cylinder 5082, and then the bottom cover side flap is inserted into the packaging box to seal the bottom cover of the packaging box.

[0085] After the above sequence of processes is completed, the push plate 503 rotates to move the packaging box to the ejection station with the movement of the fourth sliding seat 509, and under the driving of the ejection cylinder in the ejection assembly 600, the material is ejected.

[0086] The above description is an explanation of the application, not a limitation of the application, the scope of the application is defined in the claims, within the protection scope of the application, any form of modification can be made.
